Abstract: A method and apparatus for performing data error detection and correction is disclosed for multi-level logic and in particular, three-level trinary logic of levels 0, 1, 2. A source of trinary data supplies individual pieces of data (trits of 0, or 1, or 2) in multiple trit groups (trytes) to two separate check trit generators which gener­ate unique check trits for each tryte input. The check trits from the two check trit generators are compared to form syndrome trits which are used to control an error detection function. For single errors per tryte a data correction function is activated to increment or decrement the incorrect data through a multiplexer. Multiple errors or no error conditions are indicated, but do not gate the data correction function.

Abstract: A semiconductor laser device capable of emitting lights of different wavelengths has a substrate, a first light-emitting layer provided on the substrate, and a second light-emitting layer provided on the substrate and having a greater band gap than the first light-emitting layer. A barrier layer is disposed between the first and second light-emitting layers. The barrier layer has a band gap greater than those of the first and second light-emitting layers. The band gap and the thickness of the barrier layer are determined to be large enough to create, in response to injection of carriers to the light-emititng layers, a state in which the carrier density in the second light-emitting layer is made higher while the carrier density in the first light-emitting layer is made lower than those which would be obtained when the barrier layer is omitted. The device further has a pair of cladding layers sandwiching therebetween the first light-emitting layer, the barrier layer and the second light-emitting layer, the cladding layers having smaller refractive index values than the first and second light-emitting layers. The device further has electrodes for supplying electrical currents to the first and second light-emitting layers.

Abstract: 2.1 The synthesis of zeolites without using organic compounds proceeds very slowly under normal conditions, which means that there has hitherto been no purely inorganic large-scale industrial process without organic compounds for the preparation of aluminosilicates having a pentasil structure and with a high silica content. 
<??>2.2 The aim is to develop a process for the preparation of crystalline, zeolitic aluminosilicates having an SiO2/Al2O3 molar ratio of >/= 20 by hydrothermal crystallisation without using organic compounds, which process can be carried out on a large industrial scale and gives a product which is free from crystalline side phases. 
<??>The process is characterised in that the following molar ratios exist in the reaction batch:
 SiO2/Al2O3 = 20 - 60
 OH<->/SiO2 = 0.10 - 0.20
 H2O/SiO2 = 20 - 60
 and the hydrothermal crystallisation is carried out in two steps, the first step being carried out in the temperature range of from 245 to 325 DEG C for from 1 to 20 minutes and the second step being carried out in the temperature range of from 120 to 225 DEG C for from 1 to 100 hours. 
<??>2.3 A preferred application of the process relates to the purely inorganic preparation of crystalline, zeolitic aluminosilicates.

Abstract: In this method, the sample is arranged in a constant homogeneous magnetic field and irradiated in a predetermined manner with a sequence of high-frequency pulses (11, 12, 13, 17, 18, 19) and exposed to a sequence of gradient magnetic field pulses (14 to 16). This is done in such a manner that the magnetisation of the spins which is to be measured is maintained for a period which is longer than a turn-off period of the gradient magnetic field pulses (14 to 16). First, the magnetisation of only a slice of the sample is changed into a transverse magnetisation tilted by 90 DEG  in a first time interval ( tau 1). Then, volume-selective gradient magnetic field pulses (15, 16) are radiated in in a second time interval ( tau 2). In a third time interval ( tau 4), during the period of the volume-selective gradient magnetic pulses (15, 16), high-frequency pulses (17 to 19) are radiated onto the sample which change the transverse magnetisation to be measured in the volume area into a multi-pole state which is insensitive to the volume-selective gradient magnetic field pulses (15, 16) and last past the time when they are switched off. Finally, the multi-pole state is changed back to a transverse magnetisation and this is read out as signal (20) in a fourth time interval ( tau 3). …<IMAGE>…

Abstract: The functions of two virtual operating systems (e.g. S/370 VM, VSE or IX370 and S/88 OS) are merged into one physical system. Partner pairs of S/88 processors run the S/88 OS and handle the fault tolerant and single system image aspects of the system. One or more partner pairs of S/370 processors are coupled to corresponding S/88 processors directly and through the S/88 bus. Each S/370 processor is allocated form 1 to 16 megabytes of contiguous storage from the S/88 main storage. Each S/370 virtual operating system thinks its memory allocation starts at address 0, and it manages its memory through normal S/370 dynamic memory allocation and paging techniques. The S/370 is limit checked to prevent the S/370 from accessing S/88 memory space. The S/88 Operating System is the master over all system hardware and I/O devices. The S/88 processors across the S/370 address space in direct response to a S/88 application program so that the S/88 may move I/O data into the S/370 I/O buffers and process the S/370 I/O operations. The S/88 and S/370 peer processor pairs to execute their respective Operating Systems in a single system environment without significant rewriting of either operating system. Neither operating system is aware of the other operating system nor the other processor pairs.
